In my ongoing desire to increase battery life, I'm looking for a way to have the data connection (EVDO) drop (or, close) sooner. I keep FlexMail running, but I am not using IMAP's IDLE; rather, I have the program check for new messages every 15 minutes.

So, is there a setting to cause the connection to drop sooner after a period of inactivity?

Thanks in advance.
